Abstract: According to the characteristics of high containing of feldspar and quartz in a Ta-Nb concentrator tailings,a process with the removal of impurity minerals,the floatation of mica,and then the flotation of feldspar and quartz under the alkaline medium was made on the basis of mineralogy analysis.The final feldspar product with the second grade quality for the ceram and galss was obtained,and the recovery of feldspar is about 70～75%.The final quartz product with the second grade quality level for the ferrosilicium and glass was also obtained,and the recovery of quartz is about 75～80%,and the benefits between 94.60～106.52 yuan per ton ores will be made.
